I wouldn't run cats with boost, just on principle. Less restriction there is, better.
Of course I didn't have cats when I was NA so I'm slightly biased lol.
If your county has no emissions testing, no point wasting money on high flow cats

My tune is not stock. The car came from SLP with 'their' tune. Whatever a ZL600 comes with.

Since then I added SLP headers/cats, 3.4 pulley, boost-a-pump. Right after the install, the car was tuned by Steve Williams 'Tuned by Frost' @ Performance Autosport. The car actually runs a little rich. Sorry, don't have AFR numbers on hand.

I rarely ever drive the car and do not drive it hard at all. 3800 miles on it. Bought it May 2012 with 6 miles on the Odometer. When I have occasionally gotten 'into it' it runs up very smooth and pulls strong. Very happy with the way it runs.

so I have my car tuned with the high flow cats on it will I have to have my tunner adjust the tune if I get rid of them and run no cats/ or if i punch out my cats.

Yeah, I'm interested to hear this answer as well. My car has been tuned by the master (Mr Jannetty, of course) and he never once mentioned any potential for burning up my Stainless Works high-flow cats. I've been told by several guys without cats that the unburned fuel smell while sitting in traffic is pretty bad. To be honest, that was the main reason I shelled over more money for these instead of going catless. What types of symptoms do we need to be aware of that the cats are going bad??? The last thing that I want to do is harm my engine. Please advise....
